Exhaust

[AMERMUSCLE289]

Hi all,

I have a 1989 Mustang GT. It is stock except for the exhaust after the catalytic converters, which was changed to an aftermarket system. I would like to change the sound of my car a bit (make it a tiny bit louder), so I was wondering if that is possible to do with the stock catalytic converters? If so, what systems do you recommend and why?

Thanks!

Yes you are able to change out your exhaust and change the sound of your car. Without giving you a particular system (as I have never listened to the fox body exhausts much) I would suggest going to Youtube or check out some Mustang part stores like American Muscle or Late Model Restoration or CJ Pony Parts etc. and listening to the cat back exhausts that they sell on Youtube and finding one that you like.

Well just my .02 cents...I thing Mac systems on the fox body's is very hard to beat. Do go to YouTube and check out some of the Mac sit-ups. Actually just put one on ny sons 87. He got the pro chamber and cat back. Sounds pretty awesome.

Mac has a good system and relatively cheap, flow master 40 series has always been my favorite its the exhaust the started it all for mustangs (IMO). I have the Bassini 3" SS exhaust with long tube headers and H pipe. It's loud but not obnoxious, the price was right so I bought them.

Any thoughts on installing an H pipe while your there being that emissions aren't a concern?

My friend, you could swap out the mid-pipe. You can get it with high flow catalytic converters so no problems with emissions testing. Seeing how you already have an aftermarket catback, why replace it? Your choice of X or H pipe will make the exhaust a little louder plus add a little horsepower. Like my fellow NYStangers suggest listen to some exhausts on the Internet to get some ideas of sound. If you go to americanmuscle.com they have quite a few comparisons for you to check out. Their prices are good and free shipping. I see your in Suffolk county, so if you did need help I am always willing to give a hand. Installing yourself saves lots of $$$$.

Well if your in New york u need to get rid of the cats. You dont need to pass smog just safety. That would give u a big bump. I have a pair of shorty headers and catless h- pipe if u want. pm me if u interested.
